Re: OnInitDialog is not getting called from DoModal in VS2005

30-Aug-10 5:24

GenUtilLoadPropPage loads the Property Page having pageSelect.IDD. When I debugged, it was able to find the resource needed and FindResource() was successful. Wonder why it still does not call the OnInitDialog of CPpSelectDn class though.

ISOGENUTILS_DECL void GenUtilLoadPropPage(HINSTANCE hInst, CPropertyPage *pPage, int /*UINT*/ nIDTemplate)
{
    ASSERT(hInst);
    HRSRC hResInfo = ::FindResource(hInst, (LPCTSTR)nIDTemplate, (LPCTSTR)RT_DIALOG);
    ASSERT(hResInfo);
    HGLOBAL hDialogTemplate = ::LoadResource(hInst, hResInfo);
    ASSERT(hDialogTemplate);
    LPCDLGTEMPLATE pTemplate = (LPCDLGTEMPLATE)LockResource(hDialogTemplate);
    ASSERT(pTemplate);
    pPage->m_psp.dwFlags |= PSP_DLGINDIRECT;
    pPage->m_psp.pResource = pTemplate;
    pPage->SetHelpID(LOWORD((DWORD)nIDTemplate));
}

// When I debugged, it was able to find the resource needed and FindResource() was successful.

Was it in the context of the GenUtilLoadPropPage (is?)
or CPropertySheet::DoModal() (should Smile | :)

) ?

Just set a break point at the DoModal()
and then debug inside (by F11) Smile | :)

I debugged. I see that it calls 'INT_PTR CPropertySheet:: DoModal()' which internally calls CPropertySheet::OnInitDialog().

Here is the stack trace in case this helps you in pointing out any clues:

I also saw that CPropertyPage::OnSetActive() was called by CPropertySheet:: DoModal(). As can be seen above, CPropertySheet::OnInitDialog() is getting called. However, OnInitDialog function of CPpSelectDn class is not getting called.

Here is what I did with VS6.0:
- As I mentioned earlier, it was working fine with VS6.0. So What I did now is , I created a fresh VS6.0 setup on a new machine and built the code. But when I tested, again I was facing same display problem as I was getting with VS2005. However, I saw below warnings in the VS6.0 output window:

CoCreateInstance of OLE control {395262A9-51B1-11D2-BA1B-00A02489AC7A} failed.
>>> Result code: 0x800401f0
>>> Is the control is properly registered?
Warning: CreateDlgControls failed during dialog init.

So I registered the IsoDirB.ocx file using regsvr32.exe manually. Then when I tested the application with VS6.0, it worked correctly and the UI problem with Directory browser display was not there and everything worked just nicely. So this meant that if IsoDirB.ocx control is not registered, then I see UI problem with Directory browser display.

-------------------------------------------------------------------

From above findings, I also registered the IsoDirB.ocx file using regsvr32.exe manually on VS2005 machine too. It didn't give any error when I registered IsoDirB.ocx using regsvr32.exe on VS2005 machine. Then when I tested the application. However, I am still seeing the same display problem with Directory browser display with VS2005.

I see below warnings in the VS2005 output window:

'mm.exe': Loaded 'C:\Program Files\CriticalPath\Manager\IsoDirB.ocx', No symbols loaded.
First-chance exception at 0x77fac57c in mm.exe: 0xC0000139: Entry Point Not Found.
'mm.exe': Unloaded 'C:\Program Files\CriticalPath\Manager\IsoDirB.ocx'

I am not sure how much important/relevance above warning has with the UI problem; but this might be important. I remember I made changes in build of IsoDirB.ocx code project and not sure if it is causing this first chance exception. Any inputs on investigating about this "Entry Point Not Found" warning are highly appreciated.

Replace exe in Install shield

31-Aug-10 23:24

It is working fine now. I unregistered the ocx control, then rebuilt the control and then registered it with regsvr32.exe. Now OnInitDialog of CPpSelectDn is getting called. Also, the UI controls for LDAP directory browse are shown correctly on the page. It looks like earlier it had old incorrect version of ocx file registered, which needed unregistering and reregistering the new one. Wink | ;)

Hi all,
I am using Install shiield 2010 to create a setup file.
In install shield i will add all the dlls,exe and create a setup file,
So that in other system,i acn just run the setup file and use the exe.

But if any changes in the application,i dnt want to again run the install shield to just replace exe.
Is there anyother option to create a setup file through Install shield.

Where in other system i cn just replace the exe in the folders and run the setup/

Thanks
Raj

totally depend on type of install shield package you are using, if it store it's file in zip file, replace the file. that will do!

How to achieve pushbutton type effect using bitmaps

Hello there I have a issue related to the usage of the bitmap enabled Dialog window.I have created a keyboard type layout and i wish to get the input through keyboard also.When i use the mouse I am able to get the button(s) pressed and also all the buttons are working fine - the other images DEFAULT,SELECTED,DISABLED ..all get loaded and work since I am using the function here m_BtnBtn1Ctrl.LoadBitmaps ,But then any key pressed on keyboard and the corresponding character on the screen isn't able to do the same as I have been able to do it with clicking of the mouse(and using the Loadbitmaps() function ).

I am using these 3 functions to achieve the same action and effect as that using a mouse
LoadBitmap()
SetBitmap()
Invalidate()

I also tried this piece of code
HBITMAP hbm = (HBITMAP)LoadImage(NULL, "\\res\\Selected\\bitmap21.bmp", IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE);

and

bitmap.Attach((HBITMAP)LoadImage(NULL, "\\res\\Selected\\bitmap21.bmp", IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE | LR_CREATEDIBSECTION));

but these don't seem to give the pressed button effect though internally they work.Can some one please help me with this

Thanks and regards Sayonee

This is the third time that you post this question on this forum, and you posted it aloso in the Q&A.
I suggest you to make your question too clear, rather than insisting in post it as is. And again, if something on an answer is not clear, add a comment to that answer: who wrote it probably could add more explainations.

Multiple includes

Shy Agam29-Aug-10 21:49

29-Aug-10 21:49

Hello experts,

I recently solved my duplicate includes problem using the #ifndef-#define-#endif pre-processors.

However, this somehow causes a problem if classes from the same .h file should be used by different .cpp files.
The first .cpp file including the .h file gets compiled, but the others throw an "undefined reference" compile error.
It's as if I never included the .h file on the other files.

How can I overcome both duplicate includes and single includes problems?

A bit on my workstation:
OS: Ubuntu.
IDE: Eclipse.
Compiler: g++

Thanks in advance,
Shy.

That's not how include guards work. They prevent including the same header file in one compilation unit (thus, one cpp file) but doesn't prevent multiple cpp files to include the same header file.

Did you use the guards properly, e.g.

// myclasses.h
#ifndef _MYCLASSES_H_
#define _MYCLASSES_H_

// class definitions here...

#endif // _MYCLASSES_H_

// mysource1.cpp
//...
#include "myclasses.h"

// use the classes here

// mysource2.cpp
//...
#include "myclasses.h"

// use the classes here

Indeed.

However, I neglected to mention that the headers and their .cpps are in one shared-library project, and there's another project using this library.

The other project is the one which fails to compile.
It seems that this is some kind of linkage problem of some sort, but I can't figure it out.
I copied the main file form my executable project into the library project, just to see if it compiles, and it compiled perfectly.

Might I be missing on a specific linkage configuration?

Please, post the full error message.
This confirms that the problem has nothing to do with include guards, otherwise you would get a compilation error, not a linker error.
Are you sure you linked correctly to the library ?

AAMOF I'm not experienced with C++ coding.
As I am an experienced developer in other languages, I can write proper code (Or so I would like to think Wink | ;)

As far as I can tell I did link the library correctly.
Any way to make sure of it?

How did you do it ? I am not experienced with g++ so I don't know exactly how to specify library to link.
From the error you get, chances are that you didn't link to the library properly.

Are you sure you are using the ClassFromHeaderFile definitions correctly. Is GetInstance() a static member with public visibility?

No, what he's getting is an linker error. You either do not link the library which contains the definition, or you're linking in wrong order, or you haven't configured your linker properly. Please, post the makefile (or the command line) you are using to build and link the program.

This is not a COMPILER, but a LINKER ERROR.
It has nothing to deal with guards, but to the fact that your main project (not source files, that way it is defined in the IDE environment) doesn't know about the existence of the library project.

Since you're using eclipse, you should go to the main project settings and configure it to link also the artifact produced by the library project and configure the projects dependencies so that the library is always built BEFORE the main project.

This is one of the most convoluted and confused things that the eclipse CDT has. I've have to admit that -besides a good syntax parser and analyzer- for these relatively trivial things, really sucks!
